Carbon dioxide capture by a novel material that mimics a plant enzyme
A novel porous material that achieves carbon dioxide (CO2) capture-and-release with only small shifts in temperature has been developed by a team of researchers at the Center for Gas Separations Relevant to Clean Energy Technologies, led by the University of California, Berkeley Read More...
Could diesel made from air help tackle climate change?
Making diesel out of thin air sounds like something from science fiction. But small companies in Germany and Canada are doing precisely this - capturing carbon dioxide (CO2) and finding ways to sell it. German company Sunfire produced its first batches of so-called e-diesel in April. Federal Read More...
How to capture and convert CO2 from a smokestack in a single step
Using a novel catalyst, a single chemical assembly (UiO-66-P-BF2) could capture CO2 and also transform it and hydrogen into formic acid (HCOOH) via a two-step (yellow arrows) reaction (credit: Ye and Johnson/ACS Catalysis) University of Pittsburgh researchers have invented (in computations) a Read More...
Canadian scientists are tackling climate change, one air-sucking wall at a time.
Think of it as a giant, high-tech, carbon-dioxide-sucking Lego wall. …They’re a thing. We love them. We also know they’re hard to come by on the Internet. That’s why we have a team of fact-checkers double-checking everything we post, with standards that meet or exceed anyone else on the Read More...
Researchers use solar power to make carbon fiber out of thin air
Carbon capture is an idea that’s been around for a while, but it’s always seemed like a bit of an afterthought, a way to slightly slow the pace at which we’re pumping carbon dioxide into the atmosphere. But what if we could do at a scale that would suck all the carbon we’ve emitted since Read More...
New wastewater treatment method captures carbon and creates renewable energy
You may not spend much thought on cleaning up municipal and industrial wastewater, but you may have guessed it's dirty. Quite dirty, in fact. Wastewater treatment produces carbon dioxide (CO2) emissions by powering the whole machinery (and this requires high amounts of energy) and by decomposing Read More...
Electric cars are only as green as their power grid
President Barack Obama has just announced America's "first-ever national standards to limit carbon pollution from power plants." His "Clean Power Plan" calls for a 32 percent reduction in carbon dioxide emissions from 2005 levels by 2030. Why? America's electricity is still mostly coal-fired, with Read More...
Climate change dream scenario: A power plant with negative emissions
The giant coal power station at Drax in Yorkshire in the United Kingdom, with its 12 cooling towers, is one of the world’s largest greenhouse gas emitters. It sends some 23 million tonnes of carbon dioxide up its stacks each year while supplying up to a tenth of the UK’s power. But that Read More...
Where is the smog? Google will help cities find out by strapping smog-sensors to street view cars
For the past year-and-a-half, Google has been secretly testing a new way to measure the air quality in city streets. They worked together with a startup company called Aclima, to attach special sensors to its street view cars. With this sensor, they measured different chemicals that are Read More...
Welcome to our sandbox
The human race has become the single dominant force of change on the planet. We’re altering the natural world, entering the Anthropocene. That’s a good thing. Knee-deep in the blizzard of 1978, when wind-whipped sails of snow tacked across Lake Cayuga and the streets looked like a toboggan Read More...
